 a STM32 Discovery Kit using the STM32 CMSIS library and drivers
 and IAR EWARM 6.10 compiler.
 
+The CMSIS library was 21MiB compressed, so I didn't include it
+as part of this project.  The CMSIS and drivers 
+can be found by following the 'Click here for STM32
+embedded firmware' link from the resources page:
+http://www.st.com/stonline/stappl/resourceSelector/app?page=resourceSelector&doctype=FIRMWARE&SubClassID=1169
+There will be a list of firmware resources.  
+The library you are looking for is in the 
+‘ARM-based 32-bit MCU STM32F10xxx standard peripheral library’.
+Download the 
+‘ARM-based 32-bit MCU STM32F10xxx standard peripheral library’ 
+and the CMSIS library can be found in 
+'…\STM32F10x_StdPeriph_Lib_V3.4.0\Libraries\CMSIS\CM3'. 
+Copy the contents of 'CMSIS' to the 'CMSIS' folder in this project.
+and the drivers library can be found in 
+'…\STM32F10x_StdPeriph_Lib_V3.4.0\Libraries\STM32F10x_StdPeriph_Driver'. 
+Copy the contents of 'STM32F10x_StdPeriph_Driver' to the 
+'drivers' folder in this project.

 The hardware interface only uses the USART and a peripheral pin
 (RTS) for the MS/TP RS-485 interface, and the System Clock for 
 the millisecond timer.
